Some I selected for head shape and others for colour, at the same time as trying to keep the gene pool broad. There's one particularly strongly coloured male Gouldian Finch – hIs chest is darker and his feathering more iridescent than the others. You can spot him first on a branch to the right, then he pecks at a piece of millet spray for a while, then hops across the front of the dish and hangs about on a rock to the left.
I also really like the black headed hens (check out the white-breasted one), and of course the stunning red-headed, white-breasted cock birds.
They are eating soaked/sprouted finch mix seed.
BTW, the background sound is tens of thousands of Cicadas chirping. They are so loud this year!
